Abstract

The article describes the current experience in applying the diagnostics of MV cable lines in the DSO and the ongoing SORAL project. Diagnostic systems which measure partial discharges and tan delta in MV lines have been used in Poland since the turn of the century. Research work so far has focused on MV cables and on attempts to define key parameters which would indicate advanced ageing processes. However, key parameters indicating the increase in the failure risk have been identified. The research up to now is a valuable contribution to the process of creating assessment criteria for failure risk, using the IT system which automates this process. This task is carried out now in the SORAL project. Industrial research results will be the criteria for assessment of technical conditions of MV power line segments, based on technical and operational data and on diagnostic data obtained from measurements of partial discharges and tan delta. On the basis of decades-long experience in conducting diagnostic tests, and on the basis of technical and operational information gathered in GIS, the health index for specific elements of cable lines will be determined. As part of the development work, the IT system for assessment of the risk of failure of a MV power network will be built, based on assessment of technical conditions of specific elements of MV power lines. Health Index will be implemented in the SORAL system.
